Oops, had you confused with the Captain (SE V6 I think). The TSX is a slightly smaller car, but I guess the suspension would work. There is a huge aftermarket following for Hondas, so I'm sure you kind find something to fit your needs.

Actually, Honda does make the Honda performance suspension for the 03-07 Accord V6 which does in fact lower the car about 1 inch , but according to people who have installed it , its only slightly stiffer than stock and not what I would call considerably stiffer.

I think the way to go is Koni Yellows and Eibach whatever they call the smallest drop kit. Tokico has their "blue" like that might also do the trick, but those are strickly 40k mile dampers, while the Konis have maintenance but should last a lifetime.I still think I am just leaving it stock for a year and then getting something more fun.

Like I said:AEM makes a water bypass thing that supposedly keeps your motor from sucking up water.

If it keeps the water out, then you will not get the air-flow benefits of a CAI. Also a lot of CAIs suck in hot air from the engine compartment, which basically any of the negligable gains you get from a CAI.

Having too little back pressure IIRC can cause your exhaust valves to get burnt.

I believe the back pressure is in the cats, which are legally mandated so I think you could use a sewer pipe for your exhaust and still have enough back pressure to prevent injury. A Walker, Borla or Dynomax are all considered stock exhaust replacements, your you could go with a Japanese aftermarket hot-rod type. That burning exhaust valves sounds like a turbo related issue also, I don't think NA cars can get that hot.

Nope, not a Turbo issue as the turbo itself provides all the back pressure the engine needs, so anything downstream that lowers the backpressure won't lower it below the level that the turbo provides.

As for the cat itself providing back pressure, that is true to a certain extent but then putting on something after a restrictive cat (one which would provide the proper back-pressure) is irrelivent in terms of flow because the bottleneck is still in the cat.

Essentially on an NA car you will want a certain amount of back pressure in order to keep your low end torque. If you put a real big open exhaust on an NA car you'll loose a ton of low end power. If you are only doing a catback, it's mostly for the noise, not the power so it doesn't matter what you put on.

If it keeps the water out, then you will not get the air-flow benefits of a CAI.

Doesn't seem to be the case.

Also a lot of CAIs suck in hot air from the engine compartment, which basically any of the negligable gains you get from a CAI.

If its sucking hot air from the engine compartment, its not a cold air intake. CAIs only work when the car is moving though.

Nope, not a Turbo issue as the turbo itself provides all the back pressure the engine needs, so anything downstream that lowers the backpressure won't lower it below the level that the turbo provides.

I agree that the Turbo is the biggest bottleneck, but bing self sufficient for back pressure was not so much so in the case of RX7s and Supras.

As for the cat itself providing back pressure, that is true to a certain extent but then putting on something after a restrictive cat (one which would provide the proper back-pressure) is irrelevant in terms of flow because the bottleneck is still in the cat.

IMO, the very small hp gains from a catback and CAI, are usually lost in torque, which is what these engines are already lacking. All that's really gained is noise. The guy at the auto parts store will tell you what you want to hear, to get his commission. Today's cars are designed pretty well, and gains from intake and exhaust modifications are minimal (not worth the cost).

Yes but a lot of CAIs suck in hot air from the engine compartment, essentially the cold air comes through the radiator, gets nice and HOT and then is sucked in through the foam filter in the engine compartment. This allows more flow, due to being less restrictive, but negates the greater flow by sucking in hotter than normal air.

It's just so nice to finally see someone who agrees with me. I see so many guys with CAIs and "fart cans" I wonder what they really think they've gained. They see the greatly exadurated hp gains advertised by manufacturers of CAIs and catbacks, and believe it. :confuse:

Absolutely. I have been working on Subies doing mods over the years and it's amazing how many kids throw on a catback and CAI and claim they feel the power. I laugh at them. We've thrown em on for them and I've actually felt the drop in power due to the mods! Amazing

I know this is not a performance modification -- but you guys/gals would be the ones most likely to know . . . . how soon might we expect to see after-market accessories for the newly designed 08 Honda Accord? I would be very interested in replacing the front grill in my new Accord, but there are none available at this point. Any idea how long it might take? (I wish the mesh grill from the coupes would fit on the sedans -- I think they are WAY better looking!)

If you modify your car in any way, I suggest saving the original parts, so you can re-install them if and when you decide to sell the car. Modifications lower the value of the car. Not that the car is actually worth any less, it's just that many people assume modified cars have been abused.

Hello,I like to ask a question here hope some one can answer that please and thank you in advance that I have 2004 accord v6 and orignal tire size is 205/60/R16 and now i want to install 235/60/R16 snow tires on it can i do it and if yes that will it effect on performance or not let me know please as i am getting these tires pretty cheap compare to new ones so that's why thanks in advance

This would not be advisable, as it would increase your overall tire diameter more than 5%. Check out www.1010tires.com and then click on "Tire Size Calculator". You then select the original/stock tire size (205/60/16) and then compare it to the tires you are comparing it to (in this case 235/60/16). You will note that a pop-up "warning" states that anything that is more than 3% diameter change could result in brake failure.

I don't think there is enough clearance in the wheel well for a 235mm wide tire, especially when using a rim that has the stock offset. Also, I think the 235 is too wide for the stock rim so you would be looking at aftermarket wheels.

I have a new '07 AccordEXl v6 4 door with 3000 miles. Tires Michelin MXM 17" 215 50 series. Good handling, pretty quiet, and overall effect is very firm. Maybe a little too firm for me. Wondering about putting on 55 series rubber, and I've heard all kinds of negative responses: will screw up such a compurerized car, won't make a real diff, waste of money, etc. One mechanic who only does Hondas said it wouldn't hurt the car.....and one tire guy said I could mount 225width tires on the same rims and that could make a diff....SOOO, what's a guy to think? Any people out there with REAL experience with this car? Or, should I just take a pill. Let me know.

well I have a 06 V6 Accord with the same wheels and tires that you have and yes the ride is VERY firm, almost too firm but not quite. The stock Michelins are adequate at best. I agree, they handle ok but are noisy. These 17 inch tires and 50 series tires have much to do with the frim ride. I was thinking when the time comes to replace them with a H rated tire in the same size which MIGHT provide a somewhat smoother ride. Even tho I am not a big fan of Michelin tires I have read good things about the Michelin Pilot Exalto A/S in the same size as some have claimed that the ride quality on these is much better than our stock tires. Others have said to look for a touring tire instead of an all season performance tire as the softer compound of these tires may provide some smoothness. and yes, you can put on a 225 tire on that rim but I cant comment on whether or not that will help as I would think that it just gives you a wider footprint, maybe it helps I dont really know. and I dont know about your car, but I find the steering to be very heavy. Almost seems like there is no power steering. It takes some effort to steer this car off center. but maybe thats just me. Anyway, this is all just my opinion and others may disagree, but hope it helps . and good luck.

It depends on how much the overall diameter and weight increase. Larger diameter, and heavier tires will put more strain on the engine and transmission, and also affect the odometer/speedometer. It will probably look strange too, if the diameter increases an inch or more IMO. To increase the profile enough to smooth the ride, I think you would have to go with a shorter wheel. That's my opinion, and I'm sure others will differ.

I use this tool http://www.miata.net/garage/tirecalc.html to calculate the difference in size from stock or current size tire to an aftermarket one. I'd say you can probably go about 3% larger diameter w/o issue and maybe 10mm wider. The higher the sidewall the better ride you will get, so going to a 55 or even a 60 series tire in the same or wider width will improve ride. Also going with an all-season touring tire with a lower speed rating will also give you a softer better riding tire.

Thanks for your reply. Compared to the 2004 Accoord EXL 4 cyl I recently turned in, my v-6 Accord feels alot more substantial--especially in handling. It most certainly is a heavier steering feel,( car also weighs 185lbs more than my '04 4cyl )but this car tracks much better and flatter around the curves than my 4 cyl EVER did even when new. As far as alternate tires are concerned, things get expensive quick. I've read some good reviews about the Kumho Solus KH-16--a much cheaper tire, but it's so hard to know. Keep me posted if you learn anything definitive. Neil ( By the way, once your car broke in what kind of mileage were you able to achieve?)

I added a new fuel pump, radiator with 2 fan blades, power steering hose and my car seems sluggish. It seems as if I'm riding the brakes and it pulls to left side when braking. The engine light & ABS goes on. Can someone direct me to upgrading my car to a better performing car? I know I need a tune up but I'd like more horse power as well. Thanks - Jim
